  The SAP error message SADL_GW_DT_CDS037 indicates that there is a syntax issue in a Core Data Services (CDS) view that is being used in the context of the SAP Gateway. This error typically arises when the CDS view does not conform to the expected syntax or structure required by the SAP Gateway for data services.
  Cause
  The error can be caused by several factors, including:
  
  Incorrect Syntax: The CDS view may contain syntax errors or unsupported constructs that are not recognized by the SAP Gateway.
  Unsupported Features: Certain features or functions used in the CDS view may not be supported in the context of the Gateway.
  Incompatible Annotations: Annotations that are not compatible with the Gateway or that are incorrectly defined can lead to this error.
  Data Model Issues: The underlying data model may have issues, such as missing associations or incorrect data types.
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check the CDS View Syntax:
  
  Review the CDS view definition for any syntax errors. Ensure that all SQL-like constructs are correctly defined.
  Use the ABAP Development Tools (ADT) in Eclipse or the ABAP editor to check for syntax errors.
  
  
  
  Review Supported Features:
  
  Consult the SAP documentation to ensure that the features and functions used in the CDS view are supported by the SAP Gateway.
  Avoid using complex SQL constructs that may not be supported.
  
  
  
  Validate Annotations:
  
  Check the annotations used in the CDS view. Ensure that they are correctly defined and compatible with the Gateway.
  Remove or correct any annotations that may be causing issues.
  
  
  
  Test the CDS View:
  
  Execute the CDS view in the ABAP environment to see if it runs without errors. This can help isolate whether the issue is with the view itself or its integration with the Gateway.
  
  
  
  Check Data Model:
  
  Ensure that all associations and joins in the CDS view are correctly defined and that the underlying tables or views are accessible.
  Verify that the data types used in the view are compatible with the expected types in the Gateway.
  
  
  
  Debugging:
